SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 378,388, dated February 21. 1838,

Application filed August 28, 1886. Renewed September 224, 1887. Serial No. 250,584.

To aZZ whom it may concern.-

Be it known that we, LEO A. DOSCH and OLIVER L. 'Doscrr, of Miamisburg, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Shutter JVorkers, which improvement is fully set forth in the following specification and accompanying drawings, in which-- Figure l is a perspective view of our improved shutter-worker as applied, Fig. 2, a horizontal section of the window-frame and shutter, showing the device in operation; Fig. 3, an enlarged perspective View of the spindle; Fig. 4, a perspective view of one wing or member of the hinge; Fig. 5, a front view of the same, showing the method of applying the spindle thereto; Fig. 6, a perspective view of the other member of the hinge, and Fig. 7 a perspective view of Fig. 6 as removed from the sand before finishing.

Our invention relates to an improvement in shutter-workers; and it consists in the pecu liar structure of the two members of the hinge and the spindle by which they are operated, and in the combination of these parts, all of which will now be fully set forth in detail.

In the accompanying drawings, A represents the frame, and B a shutter or blind. This shutter-is hung in position at its upper end by means of an ordinary hinge, O; and in lieu of the ordinary hinge below we provide a hinge, one member of which is shown at D, Fig. 4, which has a rectangular extension, E, at one side, having outwardly therefrom journalboxings F, with a space, G, between them for the reception of a small bevel-wheel, H, as shown in Fig. 5. The outer edges of these journalboxes consist of lugs I, so disposed that the'end of the spindle J may be placed therein, and afterward the outer ends of these lugs I be clinched, the ends of the bevel-pinion H, as shown in Fig. 5, holding the said spindle in position and permitting it to rot-ate therein. A horizontal extension, K, outwardly from these journalboxings F has a vertical opening, L, therein for the reception of the vertical stem M on the opposite member N of the hinge. This section N of the hinge has laterally a central extension or wing, 0, pro vided at the end with a segmental part, P, having a section of bevel-gearing, Q, thereon.

(No model.)

Centrally within this section P is the vertical stem M, already shown as engaging with the opening L of the opposite member D of the hinge. Fig. 7shows this memberNofthehinge as shaped when it is freshly removed from the sand after casting, and as the parts of the hinge are designed to be made of malleable casting, the part of the wing 0 inwardly from the part P is twisted on a former, so as to bring the stem M parallel with the main part of the section N; and, as will be noticed, the upper hinge, C, as well as the stem M and the opening L of the member D, are such that the plate P, having on its lower side the segmental bevel-gearing Q,wil1 rest upon the small bevelwheel H. A small lug, R, on the member D, immediately above the bevel-pinion H, prevents the rising of the plate D sufficiently to prevent the gearing of the two wheels engaging with each other; but in order that the hinge may be entirely removed from the window-frame when desired, a small slot, S, is cut in the rim of the plate P in such a position that when the shutter is in a certain position the lug B may pass through it, and thus the shutter be raised from the hinges without any difficulty.

The spindle J, passing through the frame A to the inner side of the room, also passes through a plate secured to the inner edge of the frame, having a series of ratchet-teeth, U, thereon surrounding the central opening through which the spindle J passes. The knob or thumb-piece V, attached to the inner end of the spindle, is so disposed as to engage in the openings of the ratchet U, and thus prevent its being turned. For this purpose the spindle J is journaled laterally through the frame, and has a squared portion at its outer end fitting within a square central open ing of the bevel-wheel H, thus permitting the said spindle to operate freely horizontally. Thus, as will be noticed, to operate our device the spindle J is pulled inwardly somewhat, so as to disengage the knob or thumbpicce V from the ratchet U of the plate T. Then by rotating the said spindle the bevel-pinion H, engaging with the bevel-gearing on the under side of the plate T, operates the shutter as may be desired. \Vhen the shutter is closed, the spindle J is pushed outwardly, so that the IOO knob or thumbpieceV engages with the ratchet U. Thus the shutter is held securely in position when closed, and in the same manner, when the shutter is open,by engaging the knob or thumb-piece V with the ratchet U, it may be held in position, and also it may be held in any intermediate position, either partially closed or open, by simply engaging the knob with this ratchet part.

Having described our invention, what we claim as new is- 1. In a shutter-Worker,t11e adjustable spindle J, having on its outer end the thumb-piece V, combined with the ratchet-plate T, and the bevel-pinion H, and clinched lugs I, forming bearings therefor, substantially as described.

2. The combination of the spindle J, the bevel-pinion H, the ratchet-plate T, and the section D of 'the hinge, having journal F, as

described, and vertical opening L, with the section N of the hinge, having ratchet Q and vertical stem M, adapted to fit into the opening L, all substantially as described.

3. In a shutter-worker, as described, the member N, having twisted wing O,fand plate P, slotted at S in the rim, combined with the member D, having lug R, whereby, when desired, the shutter may be lifted from its hinges, substantially as described.

4. In a shutter-worker, the combination of the horizontal and adjustable spindle J. having at its inner end the thumb-piece V, the member D, having the opening L and lug R, the ratchet-plate T, and the bevel-pinion H, journaled as described, With the member N, having stem M, ratchet Q, and plate P, slotted at S, all as and for the purpose set forth.

In testimony that we claim the foregoing we have hereunto set our hands, this 4th day of May, 1886, in the presence of witnesses.
